A 3 filter Blueair 680i delivers 4x as much volume (400 cfm) of clean air (PM1, PM2.5, PM10) with an output 0 ppm (undetectably low). I can get my place (500 m^3) down to 1 ppm in 4-5 hours. No pollen, no dust, just damn clean air. Lets suppose 10 of these contraptions could accomplish the same thing owing to their less output and less efficiency: this would use several times more energy, be louder, be more maintenance, look awful, take up more outlets and space, and cost more.
I use Plantower PMS5003's, the same ones used in PurpleAir sensors.
